Check valve-less fluid-transfer collection assembly and method of using the same
First Claim
1. A method of using a fluid transfer collection assembly, comprising:
- providing a fluid transfer collection assembly including a base, a test media carried by the base, an inlet for receiving a sample fluid, an outlet, a fluid transfer path located between the inlet and the outlet, a movable and slidable first finger mechanism, a movable and slidable second finger mechanism operatively coupled to the movable first finger mechanism;
first moving at least one of the first finger mechanism and the second finger mechanism relative to the fluid transfer path so that at least one of the first finger mechanism and the second finger mechanism engage the fluid transfer path to draw the sample fluid into the fluid transfer path;
then moving at least one of the first finger mechanism and the second finger mechanism relative to the fluid transfer path so that at least one of the first finger mechanism and the second finger mechanism engage the fluid transfer path to transfer the sample fluid through the fluid transfer path to the test media,wherein the base includes a ramp assembly adjacent the inlet, the first finger mechanism includes a first flexible resilient engagement finger, and the second finger mechanism includes a second flexible resilient engagement finger, and the method further including starting with the first finger mechanism and the second finger mechanism in a home position, the home position including the first flexible resilient engagement finger urged upwards by the ramp assembly and the second flexible resilient engagement finger engaging the fluid transfer path.

Abstract
A method of using a fluid transfer collection assembly includes providing an assembly including a base, a test media carried by the base, an inlet for receiving a sample fluid, an outlet, a fluid transfer path located between the inlet and the outlet, a movable first finger mechanism, a movable second finger mechanism operatively coupled to the movable first finger mechanism; first moving at least one of the first mechanism and the second mechanism relative to the path so that at least one of the first mechanism and the second mechanism engage the path to draw the sample fluid into the path; and then moving at least one of the first mechanism and the second mechanism relative to the path so that at least one of the first mechanism and the second mechanism engage the path to transfer the sample fluid through the path to the test media.

16. A method of using a fluid transfer collection assembly, comprising:
-
providing a fluid transfer collection assembly including a base, a test media carried by the base, an inlet for receiving a sample fluid, an outlet, a fluid transfer path located between the inlet and the outlet, a movable and slidable first finger mechanism, a movable and slidable second finger mechanism operatively coupled to the movable first finger mechanism; first moving at least one of the first finger mechanism and the second finger mechanism relative to the fluid transfer path so that at least one of the first finger mechanism and the second finger mechanism engage the fluid transfer path to draw the sample fluid into the fluid transfer path; then moving at least one of the first finger mechanism and the second finger mechanism relative to the fluid transfer path so that at least one of the first finger mechanism and the second finger mechanism engage the fluid transfer path to transfer the sample fluid through the fluid transfer path to the test media; further including a limiting mechanism coupling and limiting the range of movement of the second finger mechanism relative to the first finger mechanism so that when the second finger mechanism reaches a predetermined distance relative to the first finger mechanism, the limiting mechanism causes further movement of the second finger mechanism away from the first finger mechanism to pull the first finger mechanism, and then moving includes moving the second finger mechanism relative to the first finger mechanism so that the second finger mechanism reaches a predetermined distance relative to the first finger mechanism, causing the limiting mechanism to pull the first finger mechanism so that the first finger mechanism moves and engages the fluid transfer path to transfer the sample fluid through the fluid transfer path; wherein the base includes a ramp assembly adjacent the outlet, the first finger mechanism includes a first flexible resilient engagement finger, and the second finger mechanism includes a second flexible resilient engagement finger, and the then moving further includes moving the second finger mechanism so that the second flexible resilient engagement finger is urged upwards by the ramp assembly adjacent the outlet, and moving the first finger mechanism towards the second finger mechanism so that first flexible resilient engagement finger engages the fluid transfer path to transfer the sample fluid through the fluid transfer path and out the outlet and past the second finger mechanism to the test media.
